A one dimensional simulation of the dynamic tensile test, using the finite elements method is proposed. We enlighten the consequences of a local reduction of the initial specimen section and of inertia effects, in particular on strain and strain rate history. The influence of the rheological parameter on the ductility evolution has been also studied
